Tailscaled had no way to seed device-scope syspolicy settings short of environment variables or a custom store wired up out of tree. Add a --syspolicy-file flag whose default points at a well-known JSON file that, when present, is parsed as a map[string]any and registered as a device-scope policy source. The default path is /etc/tailscale/syspolicy.json on every non-Windows platform (Linux, the BSDs, illumos/Solaris, and tailscaled-without-the-GUI on macOS) and %ProgramData%\Tailscale\syspolicy.json on Windows. The flag lets users running tailscaled by hand (development, custom installs) point it at an alternate file, and "" disables the load entirely. JSON values map to setting types as expected: strings to StringValue/PreferenceOptionValue/VisibilityValue/DurationValue (e.g. "24h" parsed by time.ParseDuration), booleans to BooleanValue, numbers to IntegerValue, and string arrays to StringListValue. The file is validated against the registered setting definitions at load time so unknown keys and value/type mismatches fail startup loudly rather than producing surprising defaults at first read. When HuJSON support is linked into the build (default; opt out with ts_omit_hujsonconf), the file may use HuJSON (comments, trailing commas). With ts_omit_hujsonconf it must be pure standard JSON. This mirrors the pattern used by ipn/conffile. On Windows the JSON file and the existing HKLM registry store both register at DeviceScope. rsop merges later-registered same-scope sources over earlier ones, so per-key values in the file override the registry while keys absent from the file fall back to the registry. The loader is registered via a feature.Hook from a file gated by !ts_omit_syspolicy, and called from main after flag parsing. tsnet still does not depend on the root syspolicy package, so embedders don't pick this up implicitly.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains the majority of Tailscale's open source code.
Notably, it includes the tailscaled daemon and
the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows,
macOS, and to varying degrees
on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's
code, but this repo doesn't contain the mobile GUI code.
Other Tailscale repos of note:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.
Using
We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.
Building
We always require the latest Go release, currently Go 1.26. (While we build releases with our Go fork, its use is not required.)
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
Signed-off-by lines in commits.
See commit-messages.md (or skim git log) for our commit message style.
